I would suggest taking it in to a brake specialist or the dealer.

I'd be happy to help you out. What model X5 do you have?

Alrighty, pads, rotors, and sensors are all different from to rear on the E53. To make things a little easier on you HERE is a link to my braking section for the E53 3.0, inside of this section we have RPS kits LINK (rotors, pads, and senors) which include very thing you need for a basic brake job. My most popular combination on the E52 is Brembo rotors with EBC RedStuff pads, this would be a performance upgrade from your stock brakes, but still be a quiet lower dusting alternative.

FYI: The Brake sensors are on the drivers side front and rear (1 front/1 rear). I would also suggest getting some brake cleaner, to clean the caliper off as well as cleaning any residual oil residue, if you decide to change the rotors front/rear (in which I would suggest doing). I went with ceramic and had to scuff up the rotors a bit because I couldn't eliminate the squeal at braking. I removed a few times, cleaning and using brake squeal stuff) However, these brakes should come with a plate on the back of the pads that helps eliminate most of it.

*I would also suggest finding a Foreign auto parts supplier to get your OEM parts from and doing your research. ECSTuning has helped you in a good direction.

You need the following:

Once you remove the tire...

* 16mm socket for the 2 caliper bolts
* Screw driver to remove the front metal spring (Use caution and be easy removing it).
* 2 or more zip ties to daisy chain or or a tall paint can or similar to secure the caliper from dropping down.
* A #6 (I believe) Allen to remove the 1 bolt securing the rotor to the hub.
* A decent mallet to help with removing the rotor by tapping it to/bottom and side to side without hitting the rotor cover.

Ensure to clean most of the residue off the caliper, a steel brush is also helpful.
Once you remove the brake pads, you will be able to notice the difference of front and back pads. The "Brake Sensor" is easily removed by pulling up in it. since you will be replacing them and throwing them out. Be careful upon the install of the new ones when you install them. They just lightly press in to the back pad with the center nipple facing the rotor.

* You will need to depress your piston on the caliper. You will need to be careful doing so. Open the hood, locate the brake fluid reservoir and open the cap just a bit to allow the fluid to easily flow back in once you depress the piston back into place. "BE CAREFUL DOING SO" You want to add even pressure while slowly pushing the piston back into the piston housing. I've use a larger clamp and thin steel plate or similar to place on the caliper piston center so it has even pressure while moving back into place. If the piston boot is damaged or out, you may want to replace that as well.

Once the piston is properly depressed, you can install the brake pads after installing the rotor making sure that it is centered to your rim bolts.

* Once brakes have been replaced and the tires are on..., "DON'T FORGET" to secure your brake fluid cap!! Start the vehicle and pump the brakes a few times to build up the resistance back into the peddle.

*Small note: If you decide to go with another brake pad options, like Bosch, some of the brake sensors may be a little shorter then the stock one's, if that is the case, simply bring in your original and have them replaced to size. It does happen.

I would stick with Brembo rotors!


Good Luck!!

Mud~
